- 1、接口实现Demo
@Service
@Component
public class UserServiceImpl implements UserService {
@Override
public String getName(int id) {
return null;
}
@Override
public User getUserById(int id) {
User user = new User();
user.setUserName("coding:Demo:"
user.setId(id);
return user;
}
@Override
public User getUser(UserParam param) {
return null;
}
}
- 2、启动类
@EnableDubbo
@SpringBootApplication
public class SduDubboServerBootApplication {
public static void main(String[] args) {
SpringApplication.run(SduDubboServerBootApplication.class, args);
}
}
- 3、application.properties
dubbo.application.name=simple
dubbo.registry.address=zookeeper://localhost:2181
dubbo.protocol.name=dubbo
dubbo.protocol.port=-1
- 4、启动结查如下：

3. Springboot-Dubbo-Client
- 主要的依赖
与server端的依赖何持一致即可：
- 主要的依赖
- 启动类
@EnableDubbo
@SpringBootApplication
public class SduDubboClientBootApplication {
@Reference
UserService userService;
public static void main(String[] args) { SpringApplication.run(SduDubboClientBootApplication.class, args).close();
System.out.println("调用完成");
}
@Bean
public ApplicationRunner getBean() {
return args -> {
System.out.println(userService.getUserById(123));
};
}
}
- application.properties
测试过程中发现服务总是无法调通。调整了一下dubbo.reference.timeout即可；
- application.properties
dubbo.application.name=youngMan
dubbo.registry.address=zookeeper://localhost:2181
dubbo.reference.timeout=5000
- 4.启动结查如下：
User{id=11, userName='coding:Demo:', age=0, sex='null'}
2019-12-08 22:34:55.429 INFO 74177 --- [pool-1-thread-1] .b.c.e.AwaitingNonWebApplicationListener : [Dubbo] Current Spring Boot Application is await...

调用完成
断开与目标 VM 的连接，地址：'127.0.0.1:62058', transport: 'socket'
4. Dubbo-admin
- 下载最新版的dubbo-admin:
git clone https://github.com/apache/dubbo-admin
- 启动dubbo-admin-server
注意为避免端口冲突，修改一下
/resource/application.properties中
server.port=8888
- 启动dubbo-admin-server
2019-12-08 21:55:06.917 INFO 65028 --- [ main] o.s.b.w.embedded.tomcat.TomcatWebServer : Tomcat started on port(s): 8888 (http) with context path ''
2019-12-08 22:16:21.561 INFO 65028 --- [nio-8888-exec-1] o.s.web.servlet.DispatcherServlet : Initializing Servlet 'dispatcherServlet'
2019-12-08 22:16:21.581 INFO 65028 --- [nio-8888-exec-1] o.s.web.servlet.DispatcherServlet : Completed initialization in 20 ms
- 启动dubbo-admin-ui
此步比较麻烦一些：
- 启动dubbo-admin-ui
- 修改config/index.js:
proxyTable: {
'/': {
target: 'http://localhost:8888/',
changeOrigin: true,
pathRewrite: {
'^/': '/'
}
}
},
- node安装：
在dubbo-admin-ui目录下执行如下命令：
npm install --registry=https://registry.npm.taobao.org
待执行完成后运行：
npm run dev
结果如下：
DONE Compiled successfully in 18504ms 10:15:55 PM
Your application is running here: http://localhost:8081
